| Abstract: | The characteristic of improved soil is important for high-speed railway, because of the strict demand of the embankment soil for high-speed railway. In the Zheng-xi high-speed passenger special railway, a large number of soil test and theoretical analyses, compactness, compressibility, strength of improved-loss and major factors influencing the engineering mechanical properties are studied. This experiment could provide a references to choice and application of roadbed filling in high-speed passenger special railway in loess region. |
